Favorable patent infringement ruling in which the court awarded the Company $48.5 million and that could result in court awarded interest costs that could add multi-millions more.

The quarterly net loss was reduced by over $0.8 million, despite business disruption from Hurricane Sandy and increased legal costs associated with the patent trial.

Enzo Life Sciences' operating income increased by $1.6 million, compared to a year ago loss.

Despite the storm-related loss of business, Enzo Clinical Labs revenues were up 7%, nearly two times the industry average growth.

Net cash used in operations was reduced by $0.8 million year-over-year to $1.5 million.

"Fiscal 2013 got off to a solid start, despite substantial, though temporary, costs of Hurricane Sandy on Enzo Clinical Labs during the final three days of the period. We are making noteworthy progress and have yet to fully benefit from the anticipated $6 million in annual cost savings that will result from last year's realignment. We anticipate that new products, operating efficiencies, enhanced marketing efforts and improved cash utilization will drive stronger operating results as the year develops," said Barry Weiner, Enzo President.

Operating Results

Sharply diminished specimen counts due to Hurricane Sandy severely impacted Enzo Clinical Labs, costing it about $0.7 million in revenue, although the Lab maintained full capabilities both during and immediately after the storm. Combined with the continued product rationalization program at Enzo Life Sciences, with the emphasis on higher margin sales, total revenues for the quarter were nonetheless on a par with year-ago results, totaling $25.6 million, compared to $25.8 million last year. Gross margins remained unchanged year over year, and gross profit as a percentage of revenues equaled 46% for both periods.

Selling, general and administrative expenses improved as a percentage of revenues to 45%, from 48%, declining just under $1.0 million. The three-week trial against Life Technologies in the Federal District Court of New Haven, CT, and expenses connected with other litigation, particularly those pending in federal court in New York City, caused an increase in legal expenditures to $1.7 million, from $0.9 million a year ago. Recent patent infringement cases filed in Wilmington, Del., are on a contingency basis and involve immaterial legal costs to the Company.

The net loss for the quarter totaled ($3.7) million, a $0.8 million reduction from a year ago, with the net loss per share at ($0.09), versus ($0.12) last year. EBITDA, a non-GAAP figure, improved by $0.5 million, to a reduced loss of ($2.6) million compared to a loss of ($3.1) million last year.

As of October 31, 2012, cash and cash equivalents amounted to $13.4 million. During the quarter cash utilized approximated $1.7 million, including cash used for legal and capital expenditures of $0.6 million. We estimate that cash collections were adversely affected by approximately $0.3 million due to the storm. Working capital equaled $18.3 million.

Operating Segments

Enzo Clinical Labs, as noted, was temporarily impacted by Hurricane Sandy, suffering no physical impairment of facilities but constrained by the weather which essentially eliminated specimen volume for three full days. For the quarter, the Lab grew revenues 7%, despite a $0.7 million effect from the storm, to $15.2 million. Gross margin rose to $5.5 million, from $5.4 million in the year-earlier period. Selling, general and administrative costs, as a percentage of revenues, improved to 33% as compared to 34% in the year ago period. The operating loss increased to $1.2 million, from $0.8 million a year ago.

Results continue to benefit from an expanded sales and marketing program, in addition to more esoteric tests being brought in-house, along with new lab tests, such as ColonSentry™ for assessing a patient's risk for having colorectal cancer at a point in time, which is being increasingly used by physicians among non-compliant individuals. The Lab has also added a new assay that assists in risk assessment and early detection of lung cancer in high risk individuals, which is being made available to physicians in the New York metropolitan market as well as New Jersey and Eastern Pennsylvania. Enzo is the only clinical laboratory making the test available within those areas.

Enzo Life Sciences posted operating income of $1.4 million, an increase of $1.6 million over a year ago when it lost $0.2 million. In line with the product rationalization program emphasizing fewer but higher margin products, net revenues declined 13%, to $8.4 million. Royalty and licensing income increased 8%, to $2.0 million. Life Sciences' gross margins improved to 60% of revenues, compared to 56% in the same period in fiscal 2012. Despite the continuing weakness in academic markets, Life Sciences is benefiting from the previously realigned business focus and the operational efficiencies implemented.

Product Development

The pipeline of new products and platforms at Enzo continues to grow. AmpiProbe™, a real time new PCR platform for detection of any nucleic acid target, which features multiple panels and greater sensitivity, is easily adaptable to most open systems and reduced cost. Assays based on this platform are awaiting approval by the New York State Department of Health. Meanwhile, Enzo continues development of new diagnostic panels, including one that would include a number of women's health diseases that would be among the most extensive available and enable diagnosis from a single specimen, saving time, patient discomfort and cost. Others would address clotting factors and various cancers.

The Company also has under development next generation branched DNA (bDNA) that includes tests for human papillomavirus, FISH (fluorescent in situ hybridization) and immunoassays where increased sensitivity is especially desirable.

NON-GAAP Financial Measures

To comply with Regulation G promulgated pursuant to the Sarbanes-Oxley Act, Enzo Biochem attached to this news release and will post to the Company's investor relations web site (www.enzo.com) any reconciliation of differences between non-GAAP financial information that may be required in connection with issuing the Company's quarterly financial results.

The Company uses EBITDA, as a measure of performance to demonstrate earnings exclusive of interest, taxes, depreciation and amortization. The Company manages its business based on its operating cash flows. The Company, in its daily management of its business affairs and analysis of its monthly, quarterly and annual performance, makes its decisions based on cash flows, not on the amortization of assets obtained through historical activities. The Company, in managing its current and future affairs, cannot affect the amortization of the intangible assets to any material degree, and therefore uses EBITDA as its primary management guide. Since an outside investor may base its evaluation of the Company's performance based on the Company's net loss not its cash flows, there is a limitation to the EBITDA measurement. EBITDA is not, and should not be considered, an alternative to net loss, loss from operations, or any other measure for determining operating performance of liquidity, as determined under accounting principles generally accepted in the United States (GAAP). The most directly comparable GAAP reference in the Company's case is the removal of interest, taxes, depreciation and amortization.
